The researchers suspect that naps especially help if you don’t normally get enough sleep or you’re getting older. They also found that napping this afternoon will have little effect on your sleep tonight.

The researchers checked the participants’ mathematical, decision making, and reaction skills. They found that participants who napped performed better immediately after the nap.

Here’s more good news – the researchers also found that the effects spilled into the next day!

So go ahead – take a nap! You have so much to do … you should get some rest!
